Psittacosis - an acute infectious disease of nature, which affects the central nervous system and lungs of a man.

causative agent of the disease is chlamydia Chlamydia psittaci, penetrating into the human body from the external environment.

causes and development of diseases

People infected with psittacosis from domestic and wild birds - canaries, parrots, pigeons, ducks, turkeys.Most often, psittacosis in humans occurs in the cold season.Epidemics and family outbreaks are rare, usually seen isolated cases of infection.

Pathogen ornithosis ingested during inhalation of dust.The dust contains microscopic particles of feces of birds, in which there are chlamydia.There are cases of psittacosis in humans following inhalation of the particles down infected individuals.

Chlamydia penetrate the body through the mucous membrane of the upper respi

ratory tract.Once they get into the smaller bronchi and bronchioles, often reaching the alveoli (the final region of the respiratory tract).As a result, the inflammatory process begins in the organs.Pathogen ornithosis replicates in the cells.If time is not started treatment, chlamydia penetrate into the bloodstream.Develops intoxication, failure of various organs and systems.The patient comes poisoning influence of the pathogen of ornithosis and products of its life.

Psittacosis is not dangerous for surrounding people.Therefore, the patient does not require isolation and hospitalization in infectious disease clinic.After an illness produced by a short-term immunity against the infection.But because of its instability, repeated infection psittacosis is quite possible.

symptoms of psittacosis

The incubation period of the disease lasts 1-3 weeks.The symptoms of psittacosis in humans depend on the form in which the disease occurs.

acute form.It is characterized by a rapid rise in body temperature to high values, headache, pain in joints and muscles, sweating, chills.These symptoms of psittacosis added sore throat, weakness, poor appetite and sleep, sometimes - nausea and diarrhea.In some patients, there is conjunctivitis, Banti's syndrome (an enlarged liver and spleen), low blood pressure, bradycardia (slowing of heart rate).Patients become irritable, whiny, agitated, suffering from insomnia.cough -

At 3-4 days another symptom of psittacosis appears from the beginning of the disease.Patients showing signs of laryngitis and tracheobronchitis, which gradually turn into pneumonia.Outbreaks pneumonia dissolve very slowly.Complete recovery usually occurs within 10-15 days.

Sometimes psittacosis is mild without lung disease.The symptoms of psittacosis in such cases are slight fever, sore throat, myalgia (muscle pain), enlargement of the spleen and liver.

chronic form.In 10-12% of patients with an acute form of psittacosis becomes chronic.The course of the disease is of the form of chronic bronchitis or defeat other systems and organs.This form of the disease can exist for several years.

Diagnosis and treatment of disease

For successful treatment of psittacosis, is very important the correct and timely diagnosis.Diagnosis of psittacosis is based on anamnesis, clinical picture of the disease, the results of laboratory and radiologic studies.The blood of a patient experienced a sharp increase in erythrocyte sedimentation rate, leukopenia (reduction in white blood cell count).

specific disease diagnosis method - allergic intradermal test containing ornitozny allergen.It is performed on day 1-5 of the disease.

When treating psittacosis in humans used antibiotics tetracycline.Taking antibiotics lasts for about a week, until the normalization of body temperature, and then for another ten days.In the case of patients hypersensitive to tetracycline antibiotics, for the treatment of psittacosis in humans using levomitsitin and erythromycin.But these drugs are less efficient and require a longer course of therapy.

In the acute phase of the disease effectively use oxygen therapy (oxygen therapy), vitamin preparations.

During the recovery of the body of the patient are used autohemotherapy.This immunotherapy, the essence of which consists in the subcutaneous or intramuscular administration to the patient his own blood, which is taken from a vein.Applying this method to the treatment of psittacosis in humans, experts say the activation of rehabilitation and defense mechanisms.

Prevention psittacosis

Prevention psittacosis includes the fight against the disease in poultry, limit contact with pigeons, regulation of their numbers.

It is very important to comply with the animal health rules for the carriage and content of the birds in zoos, poultry farms.

In order to prevent psittacosis destroy sick birds, disinfect the premises.

Persons who are at risk of infection are under medical observation for 30 days.Emergency prevention of psittacosis is carried out within ten days of doxycycline or tetracycline.
